Objective c facebook FBD在appdelegate外部登录

我已经读过很多关于facebook登录的问题，但在此之前，我没有成功地解决我的问题。到目前为止，我已经制作了一些应用程序，但我以前从未弄乱过appDelegate

问题是，我想调用我的类中的fbDidLogin方法，而不是delegate

到目前为止，appDelegate中正在调用fbdilogin，但我希望能够在登录后更改视图并请求用户信息

到目前为止，我的代码是： AppDelegate：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    facebook = [[Facebook alloc] initWithAppId:SHKCONFIG(facebookAppId) andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
    return [facebook handleOpenURL:url];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
{
    return [facebook handleOpenURL:url];
}

// This one is called correctly
- (void)fbDidLogin {
    NSLog(@"[DELEGATE] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
}

我自己的类与facebook登录按钮：

- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        NSLog(@"[LOGIN] Facebook session invalid");
        NSArray * permissions =  [[NSArray alloc] initWithObjects:
                                 @"email",
                                 @"user_birthday",
                                 nil];
        [facebook authorize:permissions];   
        [permissions release];
    } else {
        NSLog(@"[LOGIN] Facebook session valid");
        [facebook requestWithGraphPath:@"me" andDelegate:self];
    }
}
// I want this one to work so I can ask for user info at the end of it
- (void)fbDidLogin {
    NSLog(@"[LOGIN][FB] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}

如果这不清楚，我很抱歉，如果您需要更多信息，请告诉我。

您可以发布来自应用程序代表的通知，如下所示：

- (void)fbDidLogin {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"FBDidLoginCalled" object:nil];
}

然后在你的另一节课上：

- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(fbDidLoginNotificationFired) name:@"FBDidLoginCalled" object:nil]
        NSLog(@"[LOGIN] Facebook session invalid");
        NSArray * permissions =  [[NSArray alloc] initWithObjects:
                             @"email",
                             @"user_birthday",
                             nil];
        [facebook authorize:permissions];   
        [permissions release];
    } else {
        NSLog(@"[LOGIN] Facebook session valid");
        [facebook requestWithGraphPath:@"me" andDelegate:self];
    }
}
// I want this one to work so I can ask for user info at the end of it
- (void)fbDidLoginNotificationFired {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"FBDidLoginCalled" object:nil];

    NSLog(@"[LOGIN][FB] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}

您可以发布来自应用程序代理的通知，如下所示：

- (void)fbDidLogin {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"FBDidLoginCalled" object:nil];
}

然后在你的另一节课上：

- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(fbDidLoginNotificationFired) name:@"FBDidLoginCalled" object:nil]
        NSLog(@"[LOGIN] Facebook session invalid");
        NSArray * permissions =  [[NSArray alloc] initWithObjects:
                             @"email",
                             @"user_birthday",
                             nil];
        [facebook authorize:permissions];   
        [permissions release];
    } else {
        NSLog(@"[LOGIN] Facebook session valid");
        [facebook requestWithGraphPath:@"me" andDelegate:self];
    }
}
// I want this one to work so I can ask for user info at the end of it
- (void)fbDidLoginNotificationFired {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"FBDidLoginCalled" object:nil];

    NSLog(@"[LOGIN][FB] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}

我通过在-loginFacebook上添加以下代码来管理它：

myIphoneAppDelegate * MyAppDelegate = (myIphoneAppDelegate*)[[UIApplication sharedApplication] delegate];
MyAppDelegate.loginController = self;

然后，我在appDelegate上创建了登录控制器的属性，然后调用控制器-fbdilogin:

- (void)fbDidLogin {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [self.loginController fbDidLogin];
}
